Patent EP-0244649-A1 (EP)
Inventor: NIMMERSJO GUNNAR
IPC: H02H7/26
Filed: 1987-04-04
Abstract: Method and device for range limitation and direct tripping for protection in the case of a fault on a power transmission line located between two stations (P, Q) with a travelling wave model located in one of the stations (P), which travelling wave model, with the said of measured currents and voltages in the station, calculates the voltage distribution at a number of control points along the line. The range of a protection device is indicated as the distance between the measuring station and that control point for which a voltage difference (8u) becomes equal to zero. The voltage difference consists of the difference between the absolute value of a voltage difference (Au), formed as the sum of a voltage value (U") calculated with the travelling wave model for the control point at a certain time, and the corresponding voltage value (U') one half-period earlier and the absolute value of the latter voltage value. When the voltage difference becomes greater than zero, a direct tripping is initiated.

Title: A machine and method for spin flow forming rims of cylindrical metal shells
Inventor: HALASZ ANDREW
IPC: B21D19/04
Filed: 1987-05-01
Abstract: Open-ended cylindrical shells (S) for making beverage cans or containers, are necked (and/or flanged) at their open ends by tooling including a cooperating internal mandrel (42) and an external forming roller (44) while the opposite end of the shell is clamped by a chuck (40) which is rotated to spin the shell while the forming roller (44) forces the rim portion at the open end of the shell progressively into contact with the opposed mandrel (42) to form the neck (NK) and/or the flange (SL). The tooling is duplicated at regular spaced intervals around a pair of rotating wheels (12, 14); each roller (44) and anvil (42) being carried by one wheel (12) while each chuck (40) is carried by the other wheel (14); by this means, continuous production is achieved within a production loop or orbit which occupies limited space. Variations in shell thickness or metallurgy can be accommodated by employing a variable speed drive both for the chucks (40) and opposed rotatable collars (41) which fit into the open ends of the shells. The variable speed drive (86, 88) has gears driven counter to the rotation of the wheels (12, 14), this being a rotational action by which the forming operation may be performed most quickly.

Abstract: Such wall transitions, as prefabricated components, simplify the insertion of pipes or cables (26), particularly in plant buildings. They are intended to be waterproof, can be used in a versatile manner by exchanging a few parts and permit the transition of the cables or pipes at any angle with respect to the normal to the wall. This is achieved by an inner flange (24) being integrally formed on the inner circumferential surface of an outer pipe piece (20), the inner flange (24) carrying an inner pipe piece (25), whose free pipe length, at least on one side, is so long, and the free separation from the outer pipe piece is so great that a waterproof and gasproof connection can be produced to the cable or pipe passing through. This connection is expediently produced by means of a shrink sleeve (27), a shrink sleeve moulding or a rubber nozzle. <IMAGE>

Abstract: A ceramic casting composition which has been made castable by means of a plasticiser is treated with water glass in a quantity corresponding to the quantity by weight of the plasticiser. In addition, a water glass hardener is added. The casting composition is cast or moulded, dried and fired. Light aggregates and foam-forming substances can be added to the casting composition. This makes it possible to produce integrated components, i.e. components which can fulfil a plurality of tasks. In the example, the production of a ceramic plate is described which has different densities but the same chemical composition. The outer glazed layer is resistant to weathering, and the adjoining inner layer has good heat-insulating properties coupled with a low density.

Abstract: A three-dimensional curve (1 to 13) is modelled by spline sections, the totality of which specifies the path of movement of a machine tool or of a robot (R). This path of movement is approximated to the three- dimensional curve (1 to 13) in such a manner that a predeterminable tolerance band is not exceeded. The use of iterative method steps has the result that the path of movement is formed by as few spline sections as possible since the number of spline sections, if it becomes very large, could be excessive for the processing speed of a numerical control system (S) but, on the other hand, the interpolation of spline sections is a process which is technically relatively simple.
